Abstract

A musical toy has a simple construction and can accurately produce melodies and rhythms without also producing extraneous mechanical noise. A generally doll-shaped body contains two permanent magnets and is fitted with a pair of swinging members each containing an electromagnetic coil disposed so that it faces the permanent magnets. A control device, containing a rhythm signal generator circuit and a control circuit which creates rhythm drive signals based on the signal from the rhythm signal generator circuit, supplies each of the coils with a separate and independent drive signal. A sound producing body is disposed in the swinging path of each swinging member so that when the swinging member is caused by the magnetic interaction between the coil and the permanent magnets to swing in response to the rhythm signal from the control device, the sound producing body is struck by the swinging member and a musical note is sounded.

Claims6

Dependent claims

A musical toy, comprising:

(a) a toy body including a toy head mounted movably thereon and a sound producing body;
(b) a permanent magnet disposed in the toy body, a swinging member pivotally mounted on the toy body in close proximity to the permanent magnet and a head engaging member mounted on the swinging member;
(c) an electromagnetic coil, mounted on the swinging member, for causing the swinging member to swing by magnetically interacting with the permanent magnet;
(d) a control device including rhythm signal generating means for generating rhythm signals, pulse generator circuit means for producing pulse signals, control circuit means for receiving the pulse signals and the rhythm signals and in response thereto for producing rhythm drive signals, drive circuit means for receiving and supplying the rhythm drive signals to the coil;
wherein the swinging member swings in response to the rhythm drive signals and the sound producing body is positioned such that it is struck by the swinging member when the swinging member swings to produce sound and the head engaging member strikes and moves the head in concert with the sound.

A musical toy, comprising:

(a) a plurality of toy bodies, and a plurality of sound producing bodies which produce a plurality of different musical notes;
(b) a permanent magnet, and a swinging assembly mounted in close proximity to the permanent magnet, disposed on each of the toy bodies;
(c) each swinging assembly including an electromagnetic coil receiving member mounted pivotally to each toy body, an electromagnetic coil mounted on each coil receiving member for causing the coil receiving member to swing by magnetically interacting with the respective permanent magnet, each coil corresponding to one of the musical notes, each swinging assembly further including a tapper for striking one of said sound producing bodies, a spring and interconnecting means connected to said coil receiving member, said tapper connected to said interconnecting means by said spring;
(d) a control device including a microcomputer, pulse generator circuit means for generating and supplying pulse signals to the microcomputer, melody signal generating means for generating melody signals made up from a plurality of different musical notes and for supplying the melody signals to the microcomputer, drive signal supply means, the microcomputer for supply drive signals to the drive signal supply means in response to the pulse signals and the melody signals and the drive signal supplying means for supplying a drive signal for each musical note, based on the signal from the melody signal generating means, to the coil corresponding to that musical note;
wherein the coil receiving members swing in response to their respective melody drive signals and impart swinging movement to the tappers through the interconnecting means and the springs and wherein the sound producing bodies are positioned such that they are struck by the swinging tappers corresponding to their respective musical notes.
